'SHAF-T-HANG ER.

SPECIFICATION forming part of Letters Patent No. 601,885, dated April 5, 1898.

Application filed November 29,1897. Serial No. 660,139. (No model.)

clear, and exact description of the invention,

such as will enable others skilled in the art.to which it appertains to make and use the same.

My invention has relation to shaft-hangers and the object is to provide a hanger in which the bearing is universal and self-adjusting and also adjustable independent of its automatic or self adjustment.

With this object in View the invention consists of certain features of construction and combination of parts, which will be hereinafter fully. described andclaimed.

In the accompanying drawings, Figure 1 is a perspective view of a shaft-hanger. Fig. 2 is a longitudinal sectional view through the same parts. Fig. 3 is a detail perspective view of one section of the bearing, and Fig.

llS a similar View of one section of the bear ing-case.

In said drawings, 1 denotes the stationary frame of the hanger, 2 the casing supported therein, and 3 the bearing supported in the casing.

The casing consists of two counterparts a and I), each having a semicircular grooved recess 4t and provided with corresponding lugs and. recesses 5 and 6 to lock the parts together against lateral displacement. supported in the frame 1 by means of four set-screws '7, whereby the casing may be adj usted vertically or laterally.

Thebearing consists of two counterpart sections 0 0, provided along their edges with coacting recesses cl e. The inner diameter of the outer ends of the bearing-sections when .placed together are adapted to correspond with the diameter of the shaft, and theintermediate interior portions are hollowed out to form an annular hollow chamber. On the outside the bearing-sectionsare formed with semicircular convex bulges, which correspond with the grooves of the casing. These bulge portions are surrounded by the walls of the The casin g is semicircular grooves and permit of the bearin g rocking in all directions, While at the same time preventing it from becoming accidentally disengaged.

Oil-cups 8 are arranged at each end of the v bearin'gand supply oil to the hollow space therein.

While I do not wish to be confined to the particular manner of engaging the set-screws of the frame with the casing, I prefer the construction shown in the drawings, in which the casing is formed with a groove that extends entirely around it and receives the inner ends of the set-screws, thereby forming a sort of lock and preventing the casing slipping in a lateral direction, when the screws are engaged, should the screws become slightly loosened.

Although I have specifically described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the same, as such changes or modifications may be made as clearly fall within the scope of my invention without departing from the spirit. thereof.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-

1.- In a shaft-hanger, the combination with atwo-part casing, each part having asemicircular groove and coacting lugs and recesses, of a bearing consisting of two parts having coacting ribs and grooves, andprovided with semicircular convex bulges to seat in the grooves of the casing, and provided with an interior oil-chamber, substantially as set forth.

2. In a shaft-hanger, the combination with a'frame provided with radially-disposed setscrews, of a two-part casing supported in said frame, and provided with an annular central groove,and a two-part bearing having an annular curved bulge to fit in said groove to form a ball-and-socket joint,'substantially as set forth.

In testimony whereof ,I hereunto affix my signature in presence of two witnesses.
